My invention relates to fluid cooling valve or gate mechanism of the character described.

An object is to provide valve or gate apparatus adapted particularly for use inconjunction s with heated materials which come in direct contact therewith and which are 01' an abrasive character and wherein the valve apparatus is employed in a chamber through which such heated materials are passed and wherein the temperature is veryhigh. Specifically, an object is the provision of valve mechanism of this character adapted for use in the cooling chamber of a cement mill wherein heated cement clinker is impelled through the chamber and comes directly into contact with the valve mechanism.

My improved mechanism is so constructed and arranged that it may be readily cooled so as to be maintained at a non-destructive temperature and any tendency toward buckling or warping due to heat is minimized and replacement of parts is relatively easily made.

Other objects and advantages of my improved construction will more fully appear from the following specification, appended claims, and accompanying drawings wherein:

Fig. 1 is an elevation partly in section of a chamber provided with my invention,

Fig. 2 is a cross sectional view taken on 2-2 of Fig. 1,

- Fig. 3 is a cross sectional view through the hollow shaft,

Fig. 4 is a cross sectional view through the hollow shaft and valve flap,

Figs. 5, 6, and 7 are cross sectional views taken on lines 5-5, 6-6, and 7-7, respectively, of Fig. 3, and

Fig. 8 is an elevation of a fragment of the outer end oi the valve flap member.

Figs. 1 and 2 show a. construction wherein my valve mechanism is mounted and associated. The specific construction shown is that of the cooling chamber for cement clinker. In Fig. 1 this chamber is indicated generally as 10. It has a clinker intake 12 and an air exhaust 14. The inner wall is formed of reiractory.16, as shown. Thechamber is jacketed and has an outer wall 18. The space between the inner and outer walls serves as an air passageway. There is a grate over which travels a drag chain 22 which is shown as supported at one end by a drive sprocket 24 and which enters through an opening 26 in the wall of the chamber. Sealing mechanism 28 is shown at this opening 26. Air inlets 30 are provided chamber underneath W the grate and through clinker carried through counterweight 36 to hold the valve or gate at a which discharge into' the which a current of air is directed to cool the the chamber. The clinker is indicated at 32.

In a construction of the general type above specified I provide valve mechanism. This valve mechanism is shown in detail in Figs. 3 to 8. inclusive. It is shown in general assembly and in cross section in Figs. 1 and 2. Only one of the sections is here shown though a plurality would normally be provided. This valve com- 68 prises a hollow shaft illustrated in section in Fig. 3 and indicated generally by the numeral 34. This hollow shalt extends through the rei'ractory inner wall 16 and is journalled inthe outer wall 18 of the chamber as shown in Fig. 2. 10 One end of the hollow shaft is connected with a suitable source of fluid under pressure. This fluid might be air. It receives fluid from such source which enters the shaft. The other end of the shaft may be connected to a suitable de- 76 sirable apparatus. This might be' the piping about the chamber and which mightlead back to a cement kiln not shown in the drawings. The end of one shaft may be provided with a suitable determined position within the chamber. It will be seen that this counterweight holds the valve against the heated material or cement clinker so that it not only divides the chamber into compartments but serves to level of! this material.

The valve proper comprises, in addition to the hollow shaft 34, a plurality of hollow valve flap sections 38, three being here shown. These sections are arranged side by side on the shaft and 60 I are secured to a flange portion thereoi by bolts 40, as shown particularly in Figs. 3 to 7, inclusive. The flatted flange portion is indicated as 42 and appears specifically in Fig. 3. Each section is provided with a dividing baihe wall 44 extending lengthwise thereof from the shaft toward the outer end of the section. It will be seen that the shaft itself is provided with a longitudinally extending dividing wall 46 which is so no arranged as to divide the shaft into two compartments. The space on one side of the dividing wall communicates with one end of the shaft. The space on the other side of the dividing wall communicates with the other end or the shaft. Each section communicates with the shaft through two apertures. One aperture is indicated as 48 and this leads from the shaft on one side of the dividing wall into the adjacent section. The other aperture is indicated as 50 and this leads into the shaft on the opposite side of the dividing wall from each section.

The sections are provided at their outer ends with a wear resisting shoe element 52 illustrated particularly in Figs. 4, 5, and 8. This has a rounded upwardly extending portion which covers the lower part of the forward wall of each section and the shoe extends across the outer ends of the three sections closing them and being in direct communication with the interior of the sections. The shoe element is removable and may be held in place as indicated in- Figs. 5 and 8. Bolts 54 may be provided for the purpose shown.

It will appear that the cooling fluid entering the shaft at one end will pass into the several sections through the apertures ,4B"so-'thatjifluid.

of substantially the same temperature will'enter each section and will pass out of' the several sec-.

the shaft adjacent the inner wall as is more specifically described in a copending application #592,774 this day filed. The structure of the sealing mechanism for the chain at the opening through the chamber wall is likewise defined in a cppending application #592,772 of this inventor of even date and the general construction of the chamber as here provided is likewise defined in an application of this inventor of even date.
